After each repair of brake system at which the system was opened, air can get to it. After that it is necessary to remove air from system. A sign of availability of air in system is decrease in brake pressure. In this case it is necessary to eliminate a leakage of system and to remove from it air.

Air from system is removed kachatelny movements of a brake pedal. The help of the assistant is for this purpose necessary.

On HUNDRED the special device is applied to air removal from system, as a rule. By means of the specified device in system via the tank of brake liquid it is created superfluous pressure in 2.0 bar.

If it is necessary to remove air from all system, air is removed separately from each wheel. It is necessary to do it when air got to each wheel cylinder. If only one support was under repair or replaced, it is enough to remove air from the concrete cylinder, as a rule.

Sequence of removal of air the following: - Support the back right - Support the back left - Support the forward right - Cуппорт the forward left

PERFORMANCE ORDER

1. Remove a protective cap from the union of pumping of air of the brake cylinder. Clear the union, put on it a pure hose. Other end lower in the capacity half filled with brake liquid. 2. Ask the assistant to press a brake pedal so many time, how many it is necessary for creation in pressure system. Pressure in system is felt on increase of resistance of a pedal. 3. Having created necessary pressure, press a pedal to a floor. Do not release a pedal.

4. A cap key unscrew the union of removal of air approximately on one turn. Collect following liquid in capacity. Watch that the hose end constantly was in liquid. Address to an accompanying illustration.

5. After weakening of pressure of liquid close the union. 6. Repeat pedal kachaniye that pressure again was created. Again press a pedal. Open the union so that pressure fell. Close the union. 7. Repeat the described process on each brake cylinder until liquid following in capacity will not contain air vials. 8. After removal from system of air remove a hose, close the union and put on it a protective cap.

In the course of removal of air watch the tank of brake liquid. Level of liquid should not go down strongly, differently air can get to system.

Add in system only new brake liquid.

9. Similarly remove air from other brake cylinders.

10. After removal of air add brake liquid in the tank to “MAX” mark. Check a condition of sealing laying of a cover. Attention, check reliability: a) Whether brake hoses are fixed? b) Whether the brake hose in the holder is fixed? c) Whether the union of removal of air is tightened? d) Whether enough brake liquid in the tank? e) On the working engine check tightness of system. For this purpose press a brake pedal effort of 200-300 N (20-30 kg) and hold it during 10 pages. The effort of pressure of a pedal of a brake to a foot should not weaken. f) Check all connections on tightness.

11. After air removal from system the brake pedal should not be pressed through by pressing it. If it occurs, again carry out procedure of removal of air from system.
